Definitions
- the present invention refers to steering device for the support device for a rear wheel hub, that is a mechanical device that can be applied to a steering training-arm rear suspension in order to improve comfort for passengers, as well as stability.
- the rocking support device is intended to take up easily and economically the longitudinal impacts on the wheel of the motor-vehicle which are due to the impact of the wheel itself against upward projecting bumps on the road.
- the device is mounted on a support element provided with the steering lever and articulated at the end of the arm of the suspension, so that steering movements and longitudinal oscillations of the wheel in relationship to the arm itself can take place.
- rear suspensions of motor-vehicles when of the wishbone type, generally consist of a longitudinal arm the ends of which are connected to the bodywork of the motor-vehicle and the wheel hubs of the wheel, respectively.
- the ends of the arm which are not connected to the wheel are connected to the bodywork by means of bushes or bearings which are sometimes fixed to an intermediate structure called frame.
- Such a rear suspension presents many advantages, including costs of production and reduced size, yet it implies some disadvantages such as the impossibility of steering and of being provided with good longitudinal flexibility, without altering the steering when subject to steering and/or braking load. It is in fact possible to say that current suspensions are generally characterised by higher and higher levels of longitudinal flexibility of the wheel in order to achieve better capacity to take up longitudinal impacts. This tendency has affected the design of suspensions determining, on the one side, as far as conventional schemes are concerned, more attention being paid to control during steering while the wheel is moving longitudinal, by means of increasing the geometrical constraints for the areas of attachments of the arms, and on the other, the definition of new types of suspensions adapted to control separately maneuverability and comfort. However, these suspensions are very expensive.
- the wheel itself can keep itself, according to what the driver wants, at steering angles which are controlled by the steering actuator itself, by means of the proper tension rod connect 6 ed to the lever located on the steering device.
- the object is achieved by means of the present invention providing a steering device intended to achieve the steering of a support for a rear wheel-hub of a rocking wheel of a motor vehicle presenting the characteristics of claim 1 .
- FIG. 1 is a schematic perspective view of a preferred embodiment of the device according to the invention, applied to a rear wishbone suspension;
- FIG. 2 is a schematic perspective view of another preferred embodiment of the device according to the invention where the axles of the steering of the wheel is defined by means of two articulations consisting of spherical joints connecting the two ends of the wishbone to the support element of the support rocking device for the wheel-hub;
- FIG. 3 is a schematic perspective view of another preferred embodiment of the device of the invention, where the steering actuator is fixed directly to the bodywork.
- reference number 1 indicates the overall wishbone of a rear suspension for motor vehicles.
- One of the ends of the wishbone is connected to the bodywork of the motor-vehicle by means of a pivot 4 .
- the other end of the wishbone 2 divides in two parts 5 and 6 .
- the first one is provided with a spring 7 , intended to support the bodywork of the motor-vehicle, and with a damper 8 intended to dampen the oscillations of the spring.
- the second part 6 is connected, by means of a tubular seat 10 in which an axle 11 rotates on bearing 12 , to a cylindrical seat 14 .
- the cylindrical seat which is integral with the axle 11 , is basically transversal to the arm 2 and perpendicular to the longitudinal axis of the motor-vehicle.
- at least a pair of bearings 15 adapted to rotatably support a pivot 16 fixed to them or otherwise connected, are housed.
- pivot 16 is integral with a first point 18 of a connection element consisting of an elongated metal plate 19 .
- a second point 20 of plate 19 which when used faces upwards in relationship to the arm 2 of the suspension, is provided with attachments 21 for a hub 23 of the wheel, which looks towards the external part of the motor-vehicle.
- a third point 24 of the metal plate 19 is connected, in the case shown, by means of a rigid axle 25 to a bushing 26 of predefined elasticity, being integral with a support 28 integral with the cylindrical seat 14 .
- the plate 19 will be able to oscillate forwards and backwards according to the direction the motor-vehicle is moving, around the axis determined by the pivot 16 inserted into the bearings 15 .
- This oscillation that allows preventing the wheel from steering, will take place in a controlled way thanks to the elastic characteristic of the bushing 26 on which the plate 19 actuates through the axle 25 that behaves like an oscillating lever.
- the rocking device thus realized guarantees that longitudinal loads due to the impact of the wheel with the upward projecting bumps of the road are absorbed.
- the whole rocking block that is the hub of the wheel 23 , the plate 19 and the cylindrical seat 14 , either integral with each other or rotatably connected among them, is able to rotate around the axle defined by the pivot 16 supported by the bearings 12 inserted into the vertical seat 10 fixed to the wishbone 2 .
- the steering is controlled by means of an actuator 28 a , preferably an electric one, that moves tension rod 29 and makes a steering lever 30 , fixed to or integral with the cylindrical seat 14 , move.
- the conventional bushings of the suspension no longer control the longitudinal flexibility of the axle, and become radially rigid in order to nullify their effect on the divergence of the wheel and allowing their specialisation in controlling the stability of the motor vehicle.
- the device according to the invention highly improves comfort for passenger in case the overall contained weight is higher.
- FIG. 2 shows an alternative embodiment of the device according to the invention in which the axle 11 , on which the entire rocking block of the wheel, that is the wheel-hub 23 , the plate 19 and the cylindrical seat 14 rotates, is supported by means of two articulations consisting of spherical joints 31 .
- the joints connect the wishbone 2 , that divides in two ends 33 and 34 , to the cylindrical seat 14 by means of the axle 11 that passes through it.
- FIG. 3 shows another embodiment of the device according to the invention, in which the actuator 28 a is fixed on the bodywork of the motor-vehicle.
